20110243067 | DELAYED AUTOMATIC REPEAT REQUEST (ARQ) ACKNOWLEDGMENT - Disclosed are examples in which the acknowledgement channel is used for retransmitting a frame received with error. A receiver is configured to transmit an acknowledgment for a frame when the frame is decoded following receipt of the last Pilot Control Group (PCG) of the same frame. The transmitter is configured to receive the acknowledgment of an earlier frame during a subsequent frame, and not to retransmit the earlier frame. The two frames may be adjacent. During connection setup negotiation, the system can determine the values of ack_mask1 defining allowed times for the receiver to acknowledge successful decoding of the subsequent frame, and ack_mask2 defining allowed times for the receiver to acknowledge successful decoding of the earlier frame. The two mask values provide non-overlapping allowed times, so the receiver can acknowledge within the subsequent frame (1) successful decoding of the earlier frame, and (2) successful decoding of the subsequent frame. | 10-06-2011 |
